Abstract
The invention relates to a pumping pressure valve for a bicycle. The pumping pressure valve comprises a valve body, wherein two ends of the valve body respectively have an air inlet hole and an air outlet hole, the interior of the valve is provided with two inflating rubber blocks and three alloy baffle plates, and through holes are formed in the middles of the baffle plates; and the baffle plates can separate the inflating rubber blocks from each other. When the pumping pressure valve is used, the valve is installed between an air tube and an air tap of the a bicycle pump, air of the bicycle pump enters into the valve through the air inlet hole, after the pressure in a tire increases to certain extent, the rubber blocks on the side wall are extruded for inflating, the rubber blocks deform to block the small holes in the middles of the baffle plates, and air can not be pumped in to the tire by the bicycle pump. Compared with the prior art, the pumping device has the obvious advantages of small size, easiness in carrying as well as assembly and disassembly, and can prevent the bicycle pump from pumping air to the tire before air pressure in the tire reaches a critical point, so as to prevent the tire bursting phenomenon.
Description
Technical field the present invention relates to the one way of life articles for use, and especially a kind of bicycle use is inflated pressure valve.
When background technology people are used on the Floor Pump and inflate to bicycle, may occur that when tire internal pressure during to a critical value, people may not recognize, continue to inflate, and might make blowout in tire.
Summary of the invention the object of the present invention is to provide a kind of bicycle use to inflate pressure valve, before the transformation point, stops Floor Pump to be inflated in tire at the tire internal gas pressure, prevents the phenomenon of blowing out.
To achieve these goals, the present invention includes valve, be respectively equipped with induction opening and air gate at the two ends of valve, be provided with two inflating rubbers and three alloy baffle plates in the inside of valve, and be provided with open-work at the midway location place of baffle plate; Baffle plate is separated inflating rubber.
During use, with valve installation between bicycle pump tracheae and valve, the air of Floor Pump by induction opening in valve, after the tire internal pressure become greater to a certain degree, the inflated rubber of extruding sidewall, rubber generation deformation blocks aperture in the middle of the baffle plate, and then inflator can not be thrown gas in the tire into again.
The present invention compared with prior art, advantage is apparent, is mainly manifested in: small volume, be easy to carry about with one, dismounting, and air pressure that can be in tire stops Floor Pump to be inflated in tire before the transformation point, prevent the phenomenon of blowing out.
Description of drawings Fig. 1 is integral structure scheme drawing of the present invention.
Fig. 2 is the structural representation after tire internal pressure of the present invention becomes greatly.
The specific embodiment is in Fig. 1, bicycle use shown in Figure 2 are inflated the scheme drawing of pressure valve, comprise valve 1, be respectively equipped with induction opening 2 and air gate 3 at the two ends of valve, be provided with two inflating rubber 4-1 and 4-2 and three alloy baffle plate 5-1,5-2 and 5-3 in the inside of valve, and be provided with open-work 6 at the midway location place of baffle plate; Baffle plate is separated inflating rubber.During use, valve is connected between the tracheae and valve of Floor Pump.When inflating, gas is pushed inflating rubber one 4-1 open by the open-work in the middle of baffle plate one 5-1, make gas enter into valve internal, by open-work and inflating rubber two 4-2 in the middle of baffle plate two 5-2 and baffle plate three 5-3, gas enters tire, when the tire internal pressure arrives certain value, tire pressure compressing inflating rubber two 4-2, make inflating rubber two 4-2 that deformation occur, open-work in the middle of baffle plate three and the baffle plate two is blocked, then inflator can not be inflated and be entered in the tire.
